Patent CA-2267881-A1 (CA)
Inventor: HOSSEINBABAEI FARAMARZ
IPC: C25D13/02
Filed: 1999-03-25
Abstract: A process is disclosed for forming finely porous solid layers used in fabricating gas and humidity sensors, which comprises electrophoretically depositing submicron-sized particles of the said solid onto a conductive substrate from a stable or semi-stable suspension and a subsequent heat treatment. The process readily affords making of a fast resistive gas sensor comprising a finely textured porous semiconductor film and at least two ohmic contacts. In a preferred embodiment the said porous layer is deposited onto a shaped article of an alloy containing substantial amounts of aluminum, chromium and iron, where a native aluminum oxide film insulates it from the said semiconductor layer after the deposition. The process also facilitates the making of finely porous multi-layer structures for more sophisticated gas sensors.
Patent CA-2270721-A1 (CA)
Inventor: KNITTEL JIM
IPC: H04N21/61
Filed: 1999-04-29
Abstract: A bidirectional digital data communication system which generate phase coherent upstream clock and carrier signals from recovered downstream clock generated from a master clock in a central unit. The preferred species uses any downstream clock rate and generates a phase coherent upstream clock so long as the two clock rates can be related by the ratio M/N where M and N are integers. One embodiment uses an MCNS downstream and an SCDMA upstream and uses MNCN timestamp messages in the downstream to achieve an estimate of RU frame offset prior to establishing frame alignment using a ranging process. The use of timestamp messages to estimate the offset is aided by a low fitter method for inserting timestamp messages by avoiding straddling of MPEG packet headers with the sync message. Clock slip is detected by counting upstream clock cycles over a predetermined downstream clock interval and the RU transmitter is shut down if slip is detected to prevent ISI interference from misaligned codes. An SCDMA-transmitter for the minislot environment of 802.14 and MCNS is disclosed along with a receiver for the minislot environment using TDMA or SCDMA demultipiexing.

Patent CA-2278981-A1 (CA)
Inventor: KOURILOVITCH ANDREI
IPC: G01J4/04
Filed: 1999-07-23
Abstract: Field of the invention Present invention relates to an ellipsometer, a device which senses the polarization state of monochromatic light. The device measures all the parameters of the polarization state of light: the degree-of-polarization, azimuth angle and ellipticity. Since there are no moving parts, the measurement is faster and it is much lower in cost.  Therefore, this type of ellipsometer can be used for popular applications.      Description of the prior art There are many optic solutions for sensing the polarization state of light.  All of them utilize one or more polarizers , one or more waveplates and one or more photodetectors. To obtain the three parameters describing the polarization state of monochromatic light, a set of measurements has to be taken from different positions of the polarizers, waveplates or photodetectors. Therefore, data acquisition time depends on how fast the polarizers, waveplates or photodetectors are moved to their various measurement positions.  In addition, the precision of positioning the polarizers, waveplates or photodetectors influences the result of the measurement. This method of obtaining the polarization state of monochromatic light limits the use to non popular applications and needs skilled personnel to handle it.

Title: Notebook size lcd projector
Inventor: RODRIGUEZ ERNESTO M JR
IPC: G03B21/00
Filed: 1998-05-08
Abstract: A compact electronic projector (10) has separate optics and electronics compartments which are thermally and electromagnetically isolated from each other. In this manner closely spaced components are prevented from electrically or thermally interfering with each other, and high quality projected images can be maintained. The optics compartments contains a display assembly, such as a liquid crystal display panel (52) and associated Fresnel lenses, which is mounted inside the projector so as to rotate between a storage position in which the display assembly is generally parallel with the projection axis of the device, and an operational position in which the display assembly (50) is disposed at an oblique angle with relative to the projection axis. The assembly can thus be rotated to occupy the voids needed for expansion and contraction of the optical beams when the projector is in use, but which have no useful function when the projector is not in use.

Abstract: Dans deux systèmes de communication cellulaire superposés, utilisant les mêmes fréquences, dans lesquels le système de communication cellulaire supplémentaire n'a pas été pris en compte dans la planification des fréquences de l'un des systèmes de communication cellulaires, ces fréquences doivent être attribuées au système de communication cellulaire supplémentaire de manière à ne pas interférer avec le système et à ne provoquer que de faibles perturbations. L'invention a pour objet un procédé et un dispositif pour déterminer et sélectionner les fréquences. Ce procédé permet de calculer un degré de qualité en déterminant une intensité de champ moyenne f¿1?'(?), f¿2?'(?),....f¿i?'(?) de chaque fréquence possible (i=1,2,....n), en sélectionnant un nombre (N) de fréquences appropriées et leur valeur moyenne. En fonction de la qualité, une nouvelle détermination des intensités de champs moyennes de chaque fréquence est décalée dans le temps, pour pouvoir réagir lors des changements plus ou moins rapidement. En sélectionnant les valeurs en fonction de leur bonne qualité, on obtient des interférences avec le système superposé. L'invention concerne un dispositif et un procédé qui sont souples, ne permettent que de faibles interférences et de faibles perturbations parasites et sont faciles à mettre en oeuvre.

Title: A method of estimating the location of a cable break including a means to measure resistive fault levels for cable sections
Inventor: VOKEY DAVID E
IPC: B60N2/90
Filed: 2000-02-14
Abstract: A method and apparatus are used for locating cable breaks and resistive faults in cables, including fibre optic cables. The conductive shield or armour of the cable is divided into sections, usually at a splice. A step function voltage is applied to one end of the conductive shield. Remote sensors at the end of each section monitor the voltage and current as a function of time and at steady state. The measured data are encoded as current pulses and transmitted along the armour to the end of the cable. A computer at the cable end calculates from the measured voltages and currents the capacitance of each section of the shield. A broken section is identified by comparing the calculated and original capacitances of the sections and the distance along the broken section to the break is calculated from the calculated and original capacitances of the broken section. Resistive faults in the cable are located by calculating a fault resistance of each section of the shield from the measured steady state voltages and currents. A section containing a resistive fault is identified from the magnitude of the calculated fault resistance and the distance to the resistive fault is calculated from the measured steady state voltages and currents of the faulted section.

Abstract: The invention provides , for an IEEE 1394 network wherein a plurality of IEEE 1394 serial buses are connected to each other by means of a bridge, a synchronization method between the buses wherein an existing 1394 apparatus operates even if it is connected to one of the buses and a band resource of the bus is not consumed. As a network cycle master which functions as a reference clock source of an entire network, an arbitrary one portal is selected. In each bus to which the network cycle master is not connected, a portal which has the least node hop number to the network cycle master is selected as a local cycle master. The other portals which are not selected are all set as a dependent portal. The network cycle master and the dependent portals transmit a synchronizing signal to the other portals in the same bridge. Each local cycle master receives the synchronizing signal transmitted from the network cycle master or the dependent portal in the same bridge and performs control of synchronizing the cycle frequency thereof with the cycle frequency of the portal which has transmitted the synchronizing signal. Each of the network cycle master and the local cycle masters operate as a cycle master in the bus to which it is connected.
